Why the fuck does a refrigerator need to be on a network?
Controls have to be put somewhere, and networked interfaces mean fewer physical controls that may be difficult to access, tampered with or fail. Having a standard control protocol means interfaces can be changed and improved without modifying the hardware. They’re not a bad thing.
However, having networked controls exposed on anything other than private, air-gapped, wired-only LANs seems rather foolish, to me.
Speculation to your question, for monitoring and control.
For monitoring, log temperatures and send error message if it gets too high. Data could be used if any legal question come up about food spoilage.
For control, I’m guessing there’s times you want to shut it off or enable/disable defrost. Easier to do that at a computer than have controls that are either a pain inthe ass to get to, or too easy for some moron to mess with.
That being said, it should be on a local network and have no access to the internet. However a chain store would probably want the data sent to HQ, so the computer would need to be on the network.
Wouldn’t be surprised if we learned in a few months that this was done by state sponsored hackers.
2010s - We made everything smart, networked, and IOT!
2015-2025 - We need you to put your personal details into everything, everywhere, all the time!
2026-??? - We invented a machine that can hack everything on earth and steal all data for nefarious purposes.
Being “smart” and connected to the internet is about to devalue a lot of manufactured goods that have no business being either one of the those things.
The executives that allowed the system to be built this way belong in prison for the value of the destroyed food. An engineer armload certainly told them this system needed better design and security and was told no by some cheap ass trying to preserve their executive bonus.
Nothing will ever change until these monsters have personal consequences.
That was a rather cold move.
This is exactly what happened to the US Army about a month ago.
Why the fuck are all of your fridges controllable from the Internet? We didn’t have to build such a stupid, stupid society.
Attacking a countries food supply and food reserves really seems like a act of war.
The term “hackers” really downplays the severity of these kinds of cyber attacks IMO. It makes it kind of sound like a teenager in a basement somewhere, as opposed to some foreign state cyber warfare group or something along those lines.
Also it’s madness that systems like these are connected directly to the internet without read-only permissions implemented. Controls should only be accessible locally on some kind of airgap or local seperate VLAN.
The main plot of Ghost in the Shell 3. sigh
Given the simplicity of this attack and complete disregard for security by the vendor, it is likely to just be a teenager in a basement somewhere
Please stop with the acts of war or terrorism BS. The article also mentions “in-store pricing powered by electronic shelf labels” so lets not ignore this is about multi-billion companies trying to suck every penny out of our pocket. If these companies design and manufacture and buy stupid hardware that is susceptible to such hacking, they really deserve it. I mean they really do.
Second, this is a good thing. Systems will be hardened now. You think there would be any other fucking way they would upgrade their security unless something like this happens? Beatings will continue until security improves. This is why even chaotic hackers that cause damage and inconvenience are ultimately a positive force on our IT infrastructure. Think of it as an ecosystem and evolutionary pressure. Free marketplace of security models.
The disconnect between how systems “should” be and how they actually are is disappointingly enormous.
Retailers are surprisingly enough just like consumers and want things to “just work” without caring about security.
And so they get Internet-connected fridges, and it’s all fine, until the very moment it isn’t.
I hope this is a learning experience and they beef-up their systems.
And it’s not just retailers. I’ve seen this just about everywhere, especially in toxic workplaces.
I’m sure the admins managing this infra did implement strict permissions… Separate vlans are safe until you find a vulnerability in the switch OS, or find a way to access the admins account.
Just wait until some cars get hacked to accelerate as fast as possible because we just had to have telemetry in them for surveillance and profit.
Hackers using AI can absolutely hack into a Tesla and make it do anything they want. I’m surprised they haven’t to the point where it’s major news.
Hacks and attacks like this will explode with AI.
AI is absolutely incredible at finding vectors for arbitrary code execution. It can jump from layer to layer to layer to find an exploit. I want all of my appliances from now on to be dumb and not connected to the internet.
I like physical media too.
I can understand a lightweight IoT network to monitor temperatures and get alarms automatically. But why on earth would it allow controlling the fridge remotely?
It’s fucking stupid, you don’t use the manufacturer’s systems for that, or you’ll need one system for the fridges, one for the ovens, one for the lighting… You’re supposed to connect them all to YOUR control system, over isolated VLAN/LANs and then secure your system only.
Control systems will have to be air gapped going forward. This IOT fetish that the MBAs had is going to come back and bite a bunch of products in the ass.
Control systems need to be gated behind a properly secured SCADA server, then you can monitor whatever you want by connecting to your company’s VPN.
You need that if you want to let managers remotely control settings via mobile apps.
Next time, the manufacturer will learn to use a local-only protocol like Matter.
Maybe they learned they need to air gap critical infrastructure, and leave the management to on-site humans who are paid well enough not to hold their inventory for ransom.
“Learn” hahahahaha
Did having centralized control and monitoring of coolers save a fake number of man-hours on a spreadsheet instead of paying a store employee already on the clock to check temperatures occasionally?
They’re going to keep doing it because the spreadsheet says the risk is worth saving those fictional man-hour costs.
They will calculate that they spend less on recovering from these cyberattacks than they would on paying staff fairly, and carry on.
Im surprised that the EU doesnt have a secuirty requirement for IT infrastructure in the food supply. Seems like an oversight
There’s nothing as far as I know, even in industrial settings. Some companies are better than others, and some fields are better than others, but at the low level everyone does whatever the fuck they want. Always-connected teleservice routers and similar devices are everywhere, with outdated firmwares just waiting to be hacked. It’s improving but very slowly.
Erh we have the NIS2 directive… requirements are skyyyyyy high for critical infrastructure which is surprisingly a lot of industries. Among other things vulnerability management is a topic companies subject to NIS2 must cover. Not saying that it cannot happen to have outdated crap connected somewhere but the exposure is getting fast smaller and smaller.
The problem as that these directives and standards are completely beside the point. They do manage a lot of security-relevant stuff, but in the end what’s hacked isn’t the documentation the standards require but the actual code running on the machine.
And there’s pretty little that the standard can do against actual honest bugs and mistakes in the code.
Very limited scope
As in what?
As in for example this case isn’t covered
Food food supply chain isn’t covered? Isn’t it under « important entities »?
Distribution not retail
Morgan Freeman Narrating: It was in that moment, they realized the IoT was a very, very dangerous idea.
Remote monitoring 👍
Remote control 👎
David Attenborough butting in: “That’s when they should have realized it, but did not. A fatal mistake.”
What’s missing from this report is more detail on how exactly this attack went down. Did the attackers compromise supermarket networks and manipulate the fridges through lateral movement within the network; or were the fridges accessible from the open internet? If the latter is the case (and there’s a non-zero likelihood they were): why the fuck?
why the fuck
Because, despite us being in the Information Age, and computers surrounding us everywhere, only a very small portion of the population consider that learning how they work may be useful.
I’m sure if more people learned about how computers work, AI wouldn’t be a thing because they’d realize that computing-based tasks can already be automated without LLMs.
Tell that to my developer colleagues who are busy defining “skills” for the AI to do the mundane things our tools could already do. It may waste huge amounts of electricity, water and money, make us dependent on American megacorporations, cause their skills to atrophy, and be a gamble every time, but at least they don’t have to read the manual.
I had a picture of the device since I was curious, but I spotted at Walmart, and some other stores, a Cellular/Wifi/BT gateway that was branded by some company providing facilities services. As far as I can tell, the device was intended to provide secure connectivity to some service provider. I found a similar device in the freezer section of another store.
I imagine that there is remote control/remote monitoring of all the freezers or other on-premise machinery (which, is a perfectly sound thing to do), but if the central provider doesn’t take security seriously, and stay on top of their systems operations, can easily be the target for any kind of attacks.
More practically, I suspect that everyone involved has insurance whose cost is much less than ongoing proactive security + maintenance of their systems, which is why these incidents don’t seem to instantly put these companies out of business.
Stuff like eWon routers are everywhere, they’re basically openvpn (thank you open source devs, of course we won’t contribute shit or share any of the money you made us) devices that connect to a bunch of central servers and allow you to tunnel to them. Compromise such a system and you’re spoiled for choice on what to hit.
Guess…
